acoustic microstreaming and the cavitation
effect, dedicated ultrasonic inserts demonstrated
their efficacy in GTR procedures.6
Moreover, their specific shape is particularly
useful when treating deep and narrow

radiographic assessment (Figs. 1-3, p. 39),
surgery was performed as follows.
Antibiotic prophylaxis before surgery,
then every 12 hours for six days, was initiated
and the patient was instructed to rinse with
0.2% of chlorhexidine, to be continued for
two weeks after surgery. In addition, 220 mg
of naproxen sodium was administered
one hour before surgery, then twice a day
for three days.
The surgical area was anesthetized using
40 mg/mL of articaine hydrochloride with
epinephrine (1:100,000).
According to the local anatomy, access to
the defect was achieved using the modified
papilla preservation technique (Fig. 4, p. 40).
The reactive granulomatous tissue within

the intrabony defect was debrided using
Gracey curettes (Fig. 5, p. 40) and root
decontamination was carried out using
ultrasonic inserts (Fig. 6, p. 40).
The intrabony component of the defect
(Fig. 7, p. 41) was measured by means of a
15-mm periodontal probe (Fig. 8, p. 41). The
defect was grafted with a bone substitute and
a 25-by-20-by-0.2-mm collagen membrane
was trimmed using sterile scissors, positioned
to cover the defect (Fig. 9, p. 41) then
stabilized with titanium pins (Fig. 10, p. 41).
Full flap closure was achieved, and the
